SQL to JSON Converter (Seeder)
Frontend mocks and local dev environments often want JSON, but real exports are frequently SQL. This SQL to JSON converter turns INSERT INTO ... VALUES ... statements into a JSON array you can drop into a fixture file or seed script. It supports multi-row VALUES tuples, parses NULL, numbers, and booleans, and can optionally include the table name on each row. You can paste multiple INSERT statements in one go and get a single JSON array back, which makes it easy to build mock datasets for Storybook, Cypress, or local APIs. Because it runs in your browser, you can convert internal seed data without uploading SQL dumps to a third-party service.
How to Convert INSERT Statements to JSON
- Paste SQL that contains one or more
INSERT INTOstatements - Choose options like pretty JSON and table name inclusion
- Click Convert to generate a JSON array
- Copy or download the output as a
.jsonfile
Why INSERT Parsing Is Useful
INSERT statements already define structure: With column lists like (id, name, active), each tuple maps cleanly to a JSON object. Without a column list, the tool generates col1, col2, and so on.
Multi-row VALUES saves time: Many exports pack hundreds of rows into one statement. This tool reads tuples safely by tracking quotes and parentheses so strings with commas do not break the output.
Client-side conversion improves privacy: Seed data can contain emails, IDs, or internal names. Keeping everything in-browser reduces accidental data leaks.
